Clean architecture dependency rule
Which is the single most important rule of Clean/Onion architecture?
Options
- 1All layers may depend on the database layer. Persistence is the foundation everything builds on.
- 2Source-code dependencies point inward toward the domain; inner layers know nothing of outer ones
- 3The domain may import framework annotations freely. Those imports do not count as outward dependencies.
- 4Outer layers must never call inner layers. Control always originates in the innermost domain.
